The voluptuous reality star made one of the dodgiest fashion missteps in her career yesterday when she stepped out for filming in California with mum Kris Jenner.

New style rule – if a piece of clothing doesn't look good on that booty, it's time to resign it to the incinerator.

The 33-year-old's curves were wasted in an ankle-length leather skirt that looked like it had been made out of recycled bin bags. And sludge. And made by the hands of someone who hates Kim Kardashian.

The ill-fitting skirt, which wrinkled beneath Kim's astonishing rump and around the knees, didn't even seem to fit around the babe's waist, with Kim repeatedly hoisting her waistband up as she exited her 4x4.
